ATA100 Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100
controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 66/100
function. You can connect up to four hard disk drives, CD-ROM and other IDE
devices.
The Ultra ATA100  interface boosts data transfer rates between the
computer and the hard drive up to 100 megabytes (MB) per second. The new
interface is one-third faster than earlier record-breaking Ultra ATA/100
technology and is backwards compatible with the existing Ultra ATA interface.
IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a
Master and a Slave drive. You must configure second hard drive to Slave mode
by setting the jumper accordingly.
IDE2 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
MSI Reminds You...
If you install two hard disks on cable, you must configure the
second drive to Slave mode by setting its jumper. Refer to the
hard disk documentation supplied by hard disk vendors for
jumper setting instructions.

MS-6728 ATX Mainboard
The motherboard provides the following jumpers for you to set the
computer’s function. This section will explain how to change your motherboard’s
function through the use of jumpers.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external
battery to keep the data of system configuration. With the CMOS RAM, the
system can automatically boot OS every time it is turned on. If you want to
clear the system configuration, use the JBAT1 (Clear CMOS Jumper ) to clear
data.  Follow the instructions below to clear the data:
Jumpers
MSI Reminds You...
You can clear CMOS by shorting 2-3 pin while the system is off.
Then return to 1-2 pin position. Avoid clearing the CMOS while
the system is on; it will damage the mainboard.

Hardware Setup
PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are
hardware lines over which devices can send interrupt signals to the
microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT
A# ~ INT D# pins as follows:
Slots
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card.  AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory. The slot supports 8x/4x AGP card.
PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs.
When adding or removing expansion cards, make sure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion card
to make any necessary hardware or software settings for the expansion card,
such as jumpers, switches or BIOS configuration.The motherboard provides one AGP slot and five 32-bit PCI bus slots.
